Embodiment 1

[0056] In the wireless data service access system provided by Embodiment 1 of the present invention, the data service terminal 20 directly accesses an external network through the access node 10 . This access mode is generally more suitable for the situation where the data service terminal accesses the Internet network and the private network through the access node. When this access method is adopted, the protocol stack structure adopted by the access node 10 is as follows: figure 2 shown. in:

[0057] The protocol stack structure includes the physical (PHY) layer using the air interface protocol, the media access control (MediaAccess Control, MAC) layer, the radio link control protocol (Radio Link Control, RLC) layer and the radio resource control embedded in the MAC layer The protocol (Radio Resource Control, RRC) layer implements wireless data service access through the RLC layer.

[0058] Among them, the physical layer implements functions such as encoding and decodin...

Embodiment 2

[0093] In the wireless data service access system provided by Embodiment 2 of the present invention, the data service terminal 20 accesses an external network through the access node 10 and the access node gateway 30 .

[0094] The protocol stack structure adopted by the access node 10 is as follows: Figure 5 shown. The protocol stack structure includes the physical (PHY) layer using the air interface protocol, the medium access control (MAC) layer, the radio link control protocol (RLC) layer and the radio resource control protocol (RRC) layer embedded in the MAC layer. The RLC layer implements wireless data service access. For the specific functions of each layer, refer to the description of Embodiment 1.

[0095] The protocol stack structure also includes: Simplified S1 (Mini S1) interface to realize interaction of service data and service signaling with the access node gateway.

[0096] Simplifying the S1 interface can realize some basic functions that the S1 interface ...

Embodiment 3

[0109] The wireless data service access system provided by the third embodiment of the present invention integrates the function of the access node into the base station of the existing cellular network, and integrates the function of the data service terminal into the existing mobile terminal.

[0110] The structure of the integrated base station is as follows Figure 8 As shown, in addition to the existing base station, the air interface part includes: the original radio frequency module 401, the original physical layer processing module 402, the original MAC layer processing module 403, the original RLC layer processing module 404, the original PDCP layer processing module 405, the original RRC In addition to the layer processing module 406, a new MAC layer processing module 407 is also included.

[0111] The function of the MAC layer processing module 407 is the same as that of the MAC layer processing module in the first embodiment above, and may also be embedded with an ...

Abstract

The invention discloses a radio data service access method, system and device. The method comprises a radio frequency module and a radio link control (RLC) protocol layer processing module, wherein the radio frequency module is used for receiving radio data service request initiated by a data service terminal and then performing service data and service signaling interaction with the data service terminal through a radio air interface; and the RLC layer processing module is used for performing service data and service signaling interaction with an external network for providing radio data service through a network interface and enabling the data service to access to the external network. Through access nodes, the data service terminal can simply and conveniently access the external network with low cost, and the large-quantity high-speed data transmission requirement of radio data service can be met.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a wireless data service access method, system and device. Background technique [0002] In recent years, with the popularity of the mobile Internet (Mobile Internet) and smart phones, the demand for mobile data traffic has grown rapidly. According to statistics, the traffic of mobile data services is increasing at a rate of doubling every year. It is predicted that by 2014, the demand for traffic of mobile data services will reach 40 times that of 2009. The rapid growth of mobile data services has overwhelmed operators' networks and affected traditional carrier-class services. At the same time, operators need to invest more in operating costs for the rapidly growing data services year by year. [0003] The current application of mobile Internet technology drives the rapid development of broadband wireless data services, especially wireless data services are mostly...
